The TROSTEL 2.938x4.131x0.469 M/R NBR Oil Seal is engineered for industrial applications requiring dependable sealing performance, lubricant retention, and protection against contaminants in heavy-duty operating conditions.

The M/R Profile utilizes a reinforced metal outer case combined with a precision-engineered sealing lip and garter spring. This robust construction ensures dimensional stability, secure housing fitment, and consistent radial sealing force against the rotating shaft even under vibration, load fluctuations, and continuous operation.

The spring-loaded sealing lip maintains optimal contact pressure with the shaft surface, effectively preventing lubricant leakage while protecting bearings and internal components from dust, dirt, moisture, and environmental contaminants.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the sealing element offers excellent resistance to hydraulic fluids, gear oils, lubricating oils, grease, and petroleum-based lubricants. NBR remains one of the most widely used sealing materials due to its excellent wear resistance, flexibility, oil compatibility, and cost-effective performance.

With dimensions of 2.938 x 4.131 x 0.469 inch, this oil seal is commonly used in industrial pumps, hydraulic systems, agricultural machinery, industrial gearboxes, compressors, conveyor drives, and imported inch-size equipment.
